Attempts to use library net.sf.cglib.core with fc5 fail, with something like: java.lang.NoClassDefFoundError: net.sf.cglib.core.DebuggingClassWriter$1 java.lang.Class.initializeClass(libgcj.so.7) net.sf.cglib.core.DebuggingClassWriter.toByteArray(DebuggingClassWriter.java:104) net.sf.cglib.core.DefaultGeneratorStrategy.generate(DefaultGeneratorStrategy.java:64) net.sf.cglib.core.AbstractClassGenerator.create(AbstractClassGenerator.java:192) net.sf.cglib.core.KeyFactory$Generator.create(KeyFactory.java:177) net.sf.cglib.core.KeyFactory.create(KeyFactory.java:149) net.sf.cglib.core.MethodWrapper.<clinit>(MethodWrapper.java:60) java.lang.Class.initializeClass(libgcj.so.7) net.sf.cglib.core.DuplicatesPredicate.evaluate(DuplicatesPredicate.java:63) net.sf.cglib.core.CollectionUtils.filter(CollectionUtils.java:90) net.sf.cglib.reflect.FastClassEmitter.<init>(FastClassEmitter.java:106) net.sf.cglib.reflect.FastClass$Generator.generateClass(FastClass.java:100) net.sf.cglib.core.DefaultGeneratorStrategy.generate(DefaultGeneratorStrategy.java:64) net.sf.cglib.core.AbstractClassGenerator.create(AbstractClassGenerator.java:192) net.sf.cglib.reflect.FastClass$Generator.create(FastClass.java:92) net.sf.cglib.reflect.FastClass.create(FastClass.java:74) net.sf.hibernate.type.ComponentType.<init>(ComponentType.java:113) net.sf.hibernate.cfg.Binder.bindComponent(Binder.java:899) net.sf.hibernate.cfg.Binder.propertiesFromXML(Binder.java:1041) net.sf.hibernate.cfg.Binder.bindRootClass(Binder.java:363) net.sf.hibernate.cfg.Binder.bindRoot(Binder.java:1244) net.sf.hibernate.cfg.Configuration.add(Configuration.java:254) net.sf.hibernate.cfg.Configuration.addInputStream(Configuration.java:286) net.sf.hibernate.cfg.Configuration.addClass(Configuration.java:351) Others have noted this back to fedora core 4: http://xplanner.codehaus.org/XPlanner+installation+FAQ
How do I reproduce the backtrace you've pasted here?
You can't easily. That occurs deep in a complex web application (built with struts/xwork and the hibernate object relational mapper). The best I can suggest is to have a look at the same issue at: http://xplanner.codehaus.org/XPlanner+installation+FAQ
Can you try this on FC-6 when it is released? If it doesn't work then this will have to wait until we package hibernate and its dependencies for Fedora Core and Fedora Extras.
We installed Sun Java, and moved on. Our production servers are committed to fc5, sorry we can't be of help.
